Collect all Animations/Animators automatically on export and emit them as playing at the start. Animator state chains and loops will automatically be collected and exported in order as well. If this setting is off, Animators need to be registered by components – for example from PlayAnimationOnClick.
Collect all AudioSources automatically on export and emit them as playing at the start. They will loop according to their settings. If this setting is off, Audio Sources need to be registered by components – for example from PlayAudioOnClick.
Extensions to add custom behaviors and interactions to the USDZ file.
You can add your own extensions here by extending IUSDExporterExtension.

the unique identifier for this component
Enabling this option will export QuickLook-specific preliminary behaviours along with the USDZ files. These extensions are only supported on QuickLook on iOS/visionOS/MacOS. Keep this option off for general USDZ usage.
Assign the object to export as USDZ file. If undefined or null, the whole scene will be exported.
Optional
sourceholds the source identifier this object was created with/from (e.g. if it was part of a glTF file the sourceId holds the url to the glTF)
true if the object is enabled and active in the hierarchy
true if this component was destroyed (this.destroy()
) or the whole object this component was part of

updateGenerated using TypeDoc
Exports the current scene or a specific object as USDZ file and opens it in QuickLook on iOS/iPadOS/visionOS.
The USDZ file is generated using the Needle Engine ThreeUSDZExporter.
The exporter supports various extensions to add custom behaviors and interactions to the USDZ file.
The exporter can automatically collect Animations and AudioSources and export them as playing at the start.
The exporter can also add a custom QuickLook overlay with a call to action button and custom branding.
